This listing includes 2 bearings per pack.\u003c\/p\u003e\n\n\u003cp\u003eWheel bearings support the cleaner's drive wheels, allowing them to rotate freely as the unit travels across pool surfaces. Worn or seized bearings cause uneven wheel movement, reduced traction, and erratic cleaning patterns. Replacing them restores smooth, consistent wheel rotation and extends the service life of the drive wheel assembly.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eLBB91001108\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e2 per pack\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eWheel bearings on pressure-side cleaners wear gradually — by the time one wheel shows obvious drag, the others are likely close behind. When servicing the Polaris 380, 360, or 340, inspect all wheel bearings at the same time and replace as a set to avoid a repeat service call. Match the part number on your existing bearings or your cleaner's parts diagram to LBB91001108 before ordering.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-04 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53956255875347,"sku":"LBB91001108","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-hex-wheel-bearing-2-pack-polaris-380-360-340-pool-cleaner-lbb91001108.webp?v=1780435826","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_lbb91001108","provider":"Poolaroo","version":"1.0","type":"link"}
